Snap it, and it knows the words

Photograph anything around you—AI recognizes the image, pulls out multiple words, and writes everyday example sentences. Tap any word tag to hear its pronunciation.

Reminds you right before you forget

Spaced repetition (SRS) built on the Ebbinghaus forgetting curve schedules each flashcard review just as a word starts to fade—turning ‘looks familiar’ into ‘know it cold.’

Why I Built KaChiKa

Struggling with Words

Throughout my language learning journey, I constantly struggled to memorize vocabulary—learning and forgetting, wanting to speak but never knowing where to start.

A Better Way

I realized that visual memory was the key—visualizing abstract concepts made everything instantly clearer.

The Spark

Then I thought—what if we could naturally weave language learning into our daily lives and experiences?

The Mission

So I built this app, hoping to help others learn languages in a natural, visual, and context-rich way.

I built something similar with Coze before, but a real app is so much better. The UI feels great too. Hope it can extract and track grammar points someday. Huge thanks to the developer!
